asm-generic fixes for 6.10
These are some bugfixes for system call ABI issues I found while working on a cleanup series. None of these are urgent since these bugs have gone unnoticed for many years, but I think we probably want to backport them all to stable kernels, so it makes sense to have the fixes included as early as possible. One more fix addresses a compile-time warning in kallsyms that was uncovered by a patch I did to enable additional warnings in 6.10. I had mistakenly thought that this fix was already merged through the module tree, but as Geert pointed out it was still missing. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmZ9iRQACgkQYKtH/8kJ UicHIxAA0ej8dMJ3znHovc/CQYkZMpb88bxLlqLotOYuOItEzvR6wd7vnu4cPeZf nHguBiP9RAnzCZhL3F7AS3p8NNJ+P1OZo+sj6tZOANO955mzj1VQ5p2fbSRw+WI3 4Oc1HKvP6UMhHGjU3wHY0+Odd5bpoepN9/fnoiQcHPzq0LbUFM8e4D9KGr51I7fV r7tuDMy9xykEfs6umuDu9wOXih3JkpV9eSmefmjvzgxG3hKLdsvTbWVsVmnKXhZm xdFiTROOmiNvttfkQh0ruBd0drBl8aVhzCKPqIe0vQqS9rBmcf9WTkcJzpihq/fI BA3QjVQFvmHeXs+viaLZf4r/y0qabaTPRBMQxZyEFE0QgtwfxT4/ZnNEbH2s3pIC Pcm0JltLlHLbZs7V63drL6txCoFVndiPXdEBTBsqBwnuDHXCj/tvDcO3tuVTfYoz 9G8TTOsYNEDLYmn8AmzzhJOh75gp6O6A2ui3TtcD9KFNaoTQqqzPJWp8IoxBfxcb 3+rzRWQvXAhfSRBIaejv1quo2ZxoZk3KO3i+ysRITTUF1MLz7b0/Yy/8r74CqmOu 8Iw2Q0BaFPtj1x+VjneQnL++iYWYPEh+ZBEg7AD/z6QHwMLz33SyHlD+/RgRkthV J/L9xUBs5HagWJxRYkVc+l0LOVclTqVJieKD2AWONZ5OFRB+CCI= =ieQy -----END PGP SIGNATURE----- Merge tag 'asm-generic-fixes-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic fixes from Arnd Bergmann: "These are some bugfixes for system call ABI issues I found while working on a cleanup series.
